Shockwave IVL for TAVR Access Site Complications
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new method to reduce complications during Transcatheter Aortic Valve Replacement (TAVR) in patients with heavily calcified femoral arteries (arteries in the thigh hardened with calcium). The trial uses a device called the Shockwave M5 IVL Catheter to improve access to these arteries. It compares this new method to the standard procedure to determine which is more effective. Individuals with severe aortic stenosis (a serious heart valve problem) who plan to undergo TAVR, especially if their thigh arteries are heavily calcified, might be suitable for this study.
As an unphased trial, this study provides a unique opportunity to contribute to medical advancements in TAVR procedures.
Do I have to stop taking my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that the Shockwave M5 IVL Catheter is safe for TAVR access site complications?
Research has shown that the Shockwave M5 Intravascular Lithotripsy (IVL) device is safe for patients with very hard deposits in their arteries. Studies have found it to be a well-tolerated treatment, especially for those needing procedures like Transcatheter Aortic Valve Replacement (TAVR). In one study, procedures using IVL proved both safe and effective for patients with significant artery calcifications. Another study reported a high success rate of 99%, indicating the procedure was completed successfully almost every time. This suggests that the treatment is reliable and rarely causes major problems. Overall, the Shockwave M5 IVL device has demonstrated effectiveness and safety for these types of procedures.12345
Why do researchers think this study treatment might be promising?
Researchers are excited about using the Shockwave M5 Intravascular Lithotripsy (IVL) for TAVR access site complications because it offers a unique approach to dealing with heavily calcified femoral arteries. Unlike standard procedures that rely solely on mechanical and surgical techniques, the Shockwave IVL device uses sound waves to gently break up calcium deposits in the arteries, making them more pliable for catheter insertion. This method potentially reduces the risk of complications and improves outcomes by enhancing the safety and success of femoral artery access, which is crucial in procedures like TAVR.
What evidence suggests that the Shockwave M5 IVL Catheter is effective for reducing access site complications in TAVR?
In this trial, participants will receive treatment with either the Shockwave M5 IVL Catheter or standard femoral access. Studies have shown that the Shockwave M5 IVL Catheter effectively breaks down calcium build-up in arteries, aiding doctors in accessing the arteries through the leg—an important step for the TAVR heart procedure. Research indicates a very high success rate, with 99% of problem areas in arteries successfully treated using this method. Specifically, patients who received the Shockwave IVL treatment demonstrated better artery access compared to those who did not. This suggests that using the Shockwave M5 IVL Catheter could reduce complications during the procedure.12456
